I've just re-read an enjoyable light novel called Looking for the King; which is set in 1940 just before the Battle of Britain, It concerns two Americans (young man and woman) visiting England, getting caught up in a quest for the Spear of Destiny, and being helped in this search by The Inklings (and falling in love).
Over the years I have heard, from several directions, about the real and imaginary occult and magical propensities of the "National Socialist German Workers' Party" (NSGWP)*.
The idea is that there was an occult battle going-on - directed against Britain - at the same time as the war was being fought on the physical level.
Some of this material is real: for example, there was Dion Fortune's Magical Battle of Britain; or Churchill's "silent minute" - which were both supposed to mobilize the power of mass meditation and prayer, against presumed counter-forces.
On the other hand, a fair bit of the material I have encountered seems to be descended from a fictional (pretending to be factual) account by anthroposophist Trevor Ravenscroft * about Adolf's supposed quest for the Spear of Destiny Indeed this strange book seems to be a concealed and unacknowledged, but highly influential, pop-history classic.
As I mentioned before; there was indeed an important and socially-motivating spiritual dimension to the socialism and nationalism of the NSGWP; which was completely absent from the other (and even worse) totalitarian dictatorship of Lenin and Stalin in the USSR.
This means that it was rational to fear the potential for occult spiritual attack from Germany (as well as the threat of material invasion), whereas the idea would seem absurd with respect to the USSR - who had slaughtered (etc) many thousands of priests, monks and nuns; and many millions of devout Christians - in their attempt utterly to eradicate the spiritual.
But to my mind this unspirituality does not reflect to the credit of the USSR. The Communist ideology was indeed more advanced in its materialistic-evil, than was the partially-reactionary (because anti-communist) socialism of the NSGWP.
Plus, there is, and was, the influential crypto-communist aspect of the British and American ruling classes; which put the USSR as a higher priority than Britain and America.
So, even though the USSR was on the same side as Germany in 1940; and even though the USSR had, by the Battle of Britain, invaded and occupied 2/3 of the British ally Poland -- the UK did not declare war on the USSR, hardly seemed to recognize them as an enemy - and since airbrushed history and national memory accordingly.
While unconstrained fantasies of the occult and magical evil of the NSGWP (and allegorical equivalents) constitute a staple of mass media, movies, TV and novels - the greater, more enduring, and still-with-us cancer of the ideology of Communism (and its evolutionary descendants) have (during my lifetime) been almost washed-away from Western consciousness.
* I like to use the full name of the party - here in an English translation - to emphasize just how explicitly leftist they were. Socialist Worker Parties are leftist parties - but Nationalist SWPs are usually left-anti-communist. But not always. In Scotland, the Nationalists were originally also (substantially) communists (or similar); and nowadays are mainstream pro-totalitarian leftist. Anyway, the point is that the hatred between fascist and communist was a civil war of the left; not a difference between extremes.
